topology: changes to SectionPCM macros

This patch addresses the following:

1. Move PCM_PLAYBACK_ADD to pcm.m4
The macro was in the wrong m4 file (buffer.m4)

2. Remove pipeline_id argument and "index" from SectionPCM

"index" is not a member of struct snd_soc_tplg_pcm. So this
information is not used in the kernel at all.
Secondly, the PCM ID could be associated with more than
one pipeline especially in the case of DUPLEX PCM's. So better
to remove it to avoid ambiguities.

3. Remove dai_id

This dai_id is the ID given to the CPU DAI when the FE DAI link
is created. In the case of SOF, we should use an linearly increasing
unique ID for CPU DAI ID's. If this argument is omitted, the kernel
automatially assignes an ID based on the component->num_dai
which is linearly incremented every time a new DAI link is added.

4. Finally update users to align with the new definitions.
